Red Planet 4.12 — the Steamification

Red Planet is VWE's pod-racing game: eight-player VTV contests on Mars — Martian Death Race and Martian Football — originally played from inside VWE Tesla cockpit pods. This repo is the third life of that code:

Generation	What it was
Red Planet 4.10	The original game, running on the Tesla 1 pod platform (DOS-era MUNGA engine, serial RIO cockpit hardware, operator console, batch-file relaunch between missions)
Red Planet 4.11	The Win32 port of 4.10 (RP411) — DirectX 9, WinSock TCP, TeslaConsole/TeslaLauncher session control; still runs in pods, still a LAN
Red Planet 4.12	This repo: the Steamification of 4.11 — the same engine, the same wire protocol, the same missions, made distributable on Steam and playable over the internet with no cockpit hardware

The architecture is deliberately conservative: the VWE's design survives intact, with each pod-era dependency replaced by a consumer equivalent behind the engine's existing seams.

Arcade (4.10/4.11)	4.12 replacement
RIO cockpit board (serial)	PadRIO — virtual RIO from XInput pad + keyboard, fully rebindable (bindings.txt, vRIO profile format)
Seven physical displays	Single-window cockpit — all displays composed on a locked 1920×1080 canvas around the viewscreen, with the real button banks lamp-lit and clickable
Pod button lamps	On-screen lamps, plus an RGB keyboard mirror (Windows Dynamic Lighting)
TeslaConsole operator	In-game front end — race setup menu builds the mission egg locally; an in-process console marshals every race (missions still only end on a console stop, exactly as designed in 1994)
TeslaLauncher relaunch-per-mission	Single binary — menu → race → results → menu in one process
WinSock TCP LAN mesh	NetTransport seam — the deterministic pod mesh unchanged, running over plain TCP (LAN/dev) or Steam Networking Sockets (FakeIP + Steam Datagram Relay)
Site network / fixed IPs	Steam lobbies — lobby owner is the console; members exchange FakeIPs and loadouts as lobby data

Status: it works. v4.12.2 carried the first verified end-to-end internet build: three machines, three Steam accounts, lobby → mesh → marshaled five-minute race → deaths and respawns → timed stop → results on every machine → rematch from the same lobby.

v4.12.3 is about the screen. The cockpit now scales up as well as down and re-fits whenever the window changes, keeping 16:9 so a wide panel letterboxes instead of stretching; -fit runs it borderless over the whole monitor and picks the render size to land on the viewscreen 1:1. The displays are the player's to arrange — each of the six can be scaled on its own and the radar moved out of the middle of the road (environ.ini). Each display's button bank now reaches under its glass, so the picture itself is the press target rather than a sliver at the edge.

v4.12.4 is about the lobby. Both rooms now show the host's mission setup — the track, then time of day, weather and game length — since everyone flies the owner's picks and it was the one thing in the room nobody could see for themselves. The football team sheet names each player's VTV beside their team colours and position. And a lobby holds eight players rather than four, a full grid as the pod hall ran it, with the room sizing its roster to whatever space the window gives it.

v4.12.5 restores the Winners Circle. The pod hall stood the finishers on a numbered award platform when the race ended, and all of it was still in this repo — the stand, eight ranked spots in every map, and the code to put racers on them — wired only into the mission-review build and so never once run by a pod. The race now fades out and fades back in on the platform: finishers in finishing order, each pilot's callsign on the plate beside their spot, the cockpit glass cleared away, held for a few seconds before the results screen. Three pieces of it had been stubbed out in the D3D9 port and are working again.

Playing

Grab the release zip (or run pack-dist.ps1 on a build). Single player: run start-windowed.bat — the game boots into the setup menu, where the SCENARIO group picks Death Race or Football (Football swaps in the team/position columns and its own track list). Steam multiplayer: see docs/STEAM-3-MACHINE-TEST.md (until RP412 has its own AppID it runs under Spacewar, 480).

The two config files beside the exe are self-documenting: environ.ini (every engine option, commented) and bindings.txt (every key, pad button, and axis; written with the full default layout on first run). Default controls: numpad flies (8/2/4/6 stick, 7/9 pedals, 0 trigger), Shift/Ctrl throttle, Alt reverse, arrows look, Space fires, letter rows are the MFD button banks as printed on the panel. Alt+Q aborts a mission. Full map with pad and keyboard diagrams: docs/CONTROLS.md.

Building

VS 2022 (v143) + DirectX SDK June 2010 + the vendored Steamworks SDK (extern/steamworks_sdk_164) — see BUILD.md. Solution WinTesla.sln, configuration Release|Win32, output Release\rpl4opt.exe.
